Pure Maths Colloquium: Rational points on varieties via counting

Presented by Tim Browning, Bristol

25 January 2016 16:00 in CM221

I will discuss recent progress on the Brauer-Manin obstruction for rational points on algebraic varieties, before showing how counting arguments from analytic number theory
can be used to study strong approximation for a special family of varieties defined by norm forms. This allows the resolution of a conjecture of Colliot-Thelene about the sufficiency of the
Brauer-Manin obstruction for varieties admitting an appropriate fibration. This is joint work with Damaris Schindler.
